IMPROVEMENT IN CAR-COUPLINGS Specification forming part of Letters Patent No. 172,1 51, dated January 11, 1876; application filed November 19, 1e75,.

To all whom it may concern:

Be it known that I, PETER O. MURRAY, of Sloatsburg,Rockland county, New York, have invented a new and Improved Gar-Coupling, of which the following is a specification Figure 1 represents a top "iew, partly in horizontal section,of my improved car-coupling; Fig. 2, a front view of a draw-head with guide for pin-rod; and Fig. 3 is a side elevation of the coupling.

Similar letters ofreference indicate corresponding parts.

My invention relates to an improved carcoupling, by which the cars may be coupled from the side or top without danger to the attcndant, being specially adapted to cars of different heights, and forming a strong and durable coupling of the same.

Theinvention consists of acentrallyrecessed draw-head, with a stationary link attached thereto, that is coupled by the laterally-sliding cross-pin of the connecting draw-head, the pin being guided and locked in open or closed position by a side standard and pin-rod.

in the drawing, A represents a draw-head that is applied in any approved manner to the bottom-frame ot' the car. A link-frame, B, of

, tending arm, a, locked by a lateral cross-bolt,

b, to the solid rear part of the draw-head. A sidewise-extending support or arm, G, is firmly attached to the side of the draw-head, and arranged to guide the head 61 of the sliding coupling-pin 1), that passes. in lateral direction through the draw-head, and enters accurately the pin-hole at the other side of the recess, be ing guided, jointly, by the head and pin hole at the side ot'the draw-head to which the guidearm 0 is attached. The lower part of the guidearm 0 is slotted, a pin or lug, d, of the pinhead sliding therein to define the extent of sliding motion of the pin when setting the same for coupling. The coupling-pin D is operated by a rod, E, that is pivoted to the head of the pin, and provided with a downward-projecting pin or stop, e, that is introduced into the slot of the guide-arm G, as shown in Fig. 2, when the pin is moved across the drawhead for the purpose of locking thereby the coupling-link in position, and preventing its playing out of the link-frame by the vibrations of the cars; The link-frames B are tapered at the front end to pass readily sidewise of each other into the recesses of the draw'head. The pins are then pushed across the recesses, and locked by the pin-rods from the side of the car, so that the. link-frames are coupled in twofold manner.

The height of the link gives play in vertical ling may be accomplished with the same facility and absence of danger from the top of the cars as in the other case from the side.

The draw-heads may also be arranged for the common pin-and-link coupling by recessing and perforating one of the front ends for the coupling pin and link, to admit the coupling of the cars with the common coupling, when required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with pin-head d and slotted support G, of a rod, E, jointed to head, and having bottom stud 0, whereby it may be both actuated and held in the manner specified.
